"""Python3 interface implementation.
Python3 provides a class that can be used as a context manager, which
creates a temporary directory and removes it when the context manager
exits. This function emulates enough of the interface of
TemporaryDirectory, for this module to use, and is designed as a drop in
replacement that can be replaced after the python3 port.
The only user visible difference is that this does not implement the
cleanup method that TemporaryDirectory does.
